* Update load test template and config generation.
This change includes the following features and fixes:
* Add a script to generate load test examples.
* Update template generation logic to support round trip from configs to templates (handling of repeated clients and servers for the same language and of named clients and servers in source configs).
* Integrate safe language names from scenario config.
* Update template and config formatting (now that we generate in round trip).
* Fix shellcheck lint warnings.
* Update README.md.
This change fixes the format and location of the images in the driver configuration, so tests run with the proper driver configuration instead of a default.
This change adds the following features and improvements to load test generation:
* Multiple client instances are supported by setting the option `--instances_per_client`.
* `python_asyncio` is supported as a separate language.
* `php` is renamed to `php7` to match the scenario language names.
* Client and server names are shortened by the introduction of an index (`0`, `1`, ... with an optional prefix). This index replaces the uuid added to pod names when no component name is specified.
* Driver pool and image substitution are added to template generation.
* Empty entries are removed from the final configuration.
NOTE: Controller is currently not respecting driver settings from configuration, so driver is still named with a uuid. This will be addressed separately.
* Run all kokoro performance tests on dedicated node pools.
Both official and experimental tests run with kokoro are set to run on separate node pools with the suffix "-ci" (drivers-ci, workers-8core-ci, workers-32core-ci), separate from the default pools used for manual runs.
* Employ prebuilt images in continuous build.
This commits updated Kokoro build job to use prebuilt images to
run tests. The loadtest template was generated using
loadtest_template.py.
This change fixes typos and makes minor changes to the format of the generated yaml files for LoadTest configuration (embedded scenarios end in newline, and element lists are indented). The templates generated earlier are also updated.
This commit includes the following changes:
1. A new load test template generator (loadtest_template.py) is added. The template generator combines existing configurations or templates for several languages into a single template that can be used to generate configurations for different languages or combinations of languages.
2. A basic template generated from the example tests in grpc/test-infra (loadtest_template_basic_all_languages.yaml) is added.
3. The load test config generator is updated to use the combined template.
4. An example run consisting of a single test (generated from the combined template) is added and set up to run continuously.
